Passport Speaker rushing

I have a problem and i am not sure if this is a general Passport problem.
I now have my third Passport and the speakers are rushing when i play an audio or video. You can hear it clearly when you lower the volume to 1 point.

I am asking if this is a general problem because my first Passport had exactly the same problem and i had to return it. Maybe you can try this at your Passport and tell me if anyone has the same problem, didnt read about it in the forums yet.

I am getting very disappointed because the second Passport also had an issue and i had to return it. So this would be the third passport not working without problems.

I guess it's not a manufacturing or design defect but it comes from the extreme complexity inherent in smartphones nowadays...
Also, white noise is inherent in all audio systems, imagine when volume is so low and speakers are so small...

I have exact the same problem. You can hear a very loud rushing, if the speaker level on 1 or 2. Doesn't matter if you use the music app, audible app (android) or natron player (bb app). BUT, if I use headphones, I don't have rushing.

This is the reason, I changed my passport. But my second device has the same problem.

Is very annoying, if you hear audio books befor sleeping. you getting crazy. on the speaker level 1, 2 or 3, the rushing is louder than music or voice (audiobook).

I never have a problem like this before. For example. Samsong or iphone doesn't have rushing or noising, if the speaker level is low.
